Abstract

Two new species of Shairella are described: S. borowieci sp. nov. (China) and S. hsiehae sp. nov. (Taiwan). Shairella borowieci sp. nov. is the first species outside Taiwan, where all previously known species are found. It is the species with fully developed wings and capable of flight. Generic delimitation is re-evaluated and a transformation of character states is hypothesized, from normal hindwings to shortened elytra and reduced hindwings. An updated key to all known species of Shairella is provided.
